Yes, summer is the perfect time to relax and recharge. But, it’s also the perfect time to pick up a few new skills. Put that relaxed brain (and work schedule) to good use! How accomplished would you feel if, when September rolls around, you could open up your resume and add another skill to it? Very, we’re guessing.

Before you start stressing, know that we’re not asking you to sacrifice your summer nights to a droning professor, Instead, we’re suggesting devoting a few hours every week to advancing your career with an online class. (Online equals your couch and your sweats and an optional glass of wine.)
